Delve into the mysteries of the Étretat Cliffs, where Upper Cretaceous Turonian chalk might still conceal Arsène Lupin's secrets.

Step into the shoes of a 1900s detective, following in the footsteps of Maurice Leblanc and his gentleman burglar, Arsène Lupin. Your mission takes you to Étretat, in Haute-Normandie, to solve a mystery buried beneath the white chalk cliffs that inspired Claude Monet and Eugène Isabey. At each stage of your thematic circuit, open your phone: augmented reality clues are revealed on the flint strata, ancient pebbles, or village facades. Lupin's silhouette appears on the Étretat Needle, a coded letter forms on the Porte d'Aval, and Gustave Courbet's works come to life on the Manneporte. Over 1 to 3 days, at your own pace, you trace your own investigation through this remarkable landscape of the Côte d'Albâtre, combining geological heritage and literary fiction. More than an outdoor escape game: an interactive visit immersed in the history of Normandy France, with anecdotes revealed at each stop and confidential sites that classic guides overlook.

The story that haunts this land

Votre enquête débute Place Maurice Guillard, face au front de mer d'Étretat. De là, vous observez les Falaises d'Amont, formées il y a 90 à 100 millions d'années durant le Crétacé supérieur. Ces parois, composées de craie turonienne dite 'du Tilleul', dépassent 90 mètres de hauteur et sont striée de silex. En suivant les sentiers côtiers, vous découvrez l'ingénierie naturelle des lieux : les trois arches principales, dont la Porte d'Amont, n'ont pas été creusées par l'érosion marine directe, mais par l'eau de pluie et les rivières souterraines. Cette visite interactive d'Étretat vous révèle les secrets géologiques du patrimoine Normandie.

Poursuivez votre visite d'Étretat vers l'Aiguille d'Étretat, un témoin géologique de 51 mètres de haut dont la découpe remonte entre 2 000 et 5 000 ans. Ce monolithe, apparaissant sur des cartes romaines, est devenu le repaire imaginaire du célèbre Arsène Lupin, le gentleman cambrioleur créé par Maurice Leblanc. C'est ici que le personnage de fiction dissimulait ses trésors. En réalité augmentée, vous pourriez bien déceler des indices cachés par le maître du déguisement, rendant ce site un point central de votre jeu de piste GPS à travers la Côte d'Albâtre.

Le chemin vous mène ensuite à la Porte d'Aval, une immense arcade de silex située à gauche de la plage d'Étretat. Contrairement aux arches d'Amont, celle-ci fut creusée par les vagues battant l'extrémité de la falaise au fil des millénaires. La roche siliceuse de la Porte d'Aval contraste avec la craie blanche environnante, offrant un paysage remarquable. À proximité, la Manneporte, autre arche principale, fut rendue célèbre par les toiles de Claude Monet et Gustave Courbet au XIXe siècle. Ces peintres ont immortalisé ces formations naturelles, originellement sculptées par les rivières souterraines avant l'action marine, contribuant à la renommée internationale des Falaises d'Étretat.

De retour au Village d'Étretat, vous explorez son front de mer. Le village, situé en cuvette, est protégé par une digue naturelle de galets dont la forme arrondie est l'œuvre de l'action marine. Découvert comme destination touristique par le peintre Eugène Isabey en 1820, Étretat s'est désenclavé avec l'arrivée de la ligne de chemin de fer en 1895. Les toiles de Claude Monet, dont la cote artistique a atteint des sommets, ont ensuite popularisé ce lieu internationalement. Votre roadtrip Normandie vous fait revivre cette époque, en vous immergeant dans l'histoire de la ville.

Votre exploration se termine par la Chapelle Notre-Dame de la Garde, perchée au sommet des Falaises d'Amont. De là, vous contemplez les plages voisines d'Yport et Vaucottes, des plages de galets grisâtres caractéristiques de la Haute-Normandie, accessibles par la route côtière. Ces sites, faisant partie du même système géologique de falaises de craie, complètent votre compréhension du patrimoine géologique Crétacé de la région. Ce circuit thématique, entre fiction et réalité, vous offre une visite interactive d'Étretat unique, vous laissant avec une compréhension profonde des paysages et de l'imaginaire qui y sont liés, et pourquoi ce site est un projet labellisation Grand Site.
